Abstract

This research explores the intermodulation effect between high-intensity ultrasonic waves with slightly differing frequencies. It investigates the generation of a directional, low-frequency sound beam using the intermodulation effect with a parametric acoustic array (PAA), along with analysis aimed on the improvement of the PAA's design. Moreover, the reduction of unwanted distortions is achieved by optimizing the driving signal. The impact of the sound field generated by the PAA on a low-frequency signal emitted by an external sound source is also investigated. The research involves both numerical simulations and laboratory experiments.
